Anprolene Pump Failure

In this worst-case scenario study, an Anprolene AN74i was operated in a room without air circulation and with a simulated ventilation pump failure when the gas concentration was highest.

Air samples were taken when the pump “failed” and 40 min later. At both points, gas concentrations were well below OSHA STEL. Researchers concluded operators are not at risk of EO exposure should the vent pump fail during an AN74i cycle, even at times of peak concentration.
